TYPEWRITING- MACHINE.

Application filed May 23,

To all. whom it may concern:

Beit known that I, BURNHAM C. STIcK- NEY, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to the application of mechanism of the continuous billing or fan-fold type to bookkeeping machines of the Underwood-Hanson type, and is in the nature of an improvement on the invention disclosed in my prior application, Serial No.

489,990, filed August 5, 1921.

When fan-fold mechanism is applied to a bookkeeping machine of the type referred to, the webs must be guided above the usual housing of each set of denominational jacks,

thereb rendering it difficult to straighten the welds sufliciently under the platen to permit the carbons to be withdrawn by the usual carbon-carrier. Moreover, due to the mounting of the typewriting machine on the computer casing, provision must be made of a suitable support, different from that in,the usual fan-fold machines, for the rear rail on which the rear end of the carbon-carrier track travels. Furthermore, it is desirable to support the carbon-carrier track in such a manner as to permit access to the parts at the back of the machine.

In carrying out the invention, use is made at each end of the platen of an oversized broad pinion for connecting the gear on the adjacent end of the platen axle with the SlIl'lilar gear on the stub-shaft journaled in the adjacent end of the carriage. By using oversized broad pinions, it is rendered possible to 40 locate the shafts, carrying the broad pinions and about which the platen-lifting frame swings, at such a position that the platenmay be raised to a greater extent than in the ordinary fan-fold machine.

The front end of the carbon-carrier track may be pivotally supported immediately above the rear end of a j ack-housing mounted at the rear of the typewriter. This housing slopes downwardly toward the rear, and

the front end of the carbon-carrier trackmay, therefore, be in a lower position than it would be if the front end of the track were mounted above the front end of the housing or still farther to the front. This position of the forward end of the track also 1922. serial no. aeaeea.

renders the machine more open at the top so that access may readily be had to the denomination-selectors.

In said prior application, the rear rail on which the carbon-carrier track travels transversely of the machine is mounted on a bracket or support secured to the rear of the typewriter frame. Such an arrangement interferes, however, with access to the denomlnation-selecting mechanism and other parts at the rear of the typewriter frame. According to the present invention, the bracket, on which said rear rail is mounted, 1s supported on the stand on which the computer casing rests, thus providing sufiicient room between the upper part of the bracket and the back of the bookkeeping machine to permlt access thereto. Although the weight to be supported by said bracket is small, it is necessary to make said bracket of considerable strength to prevent the same from being bent out of shape by actual collisions therewith. The bracket or support for the rear rail may be so constructed that it may be attached to the usual form of stand for a W bookkeeping machine without any change in the construction of the stand.

To support the front end of the carboncarrier track, provision may be made of brackets, 'one for each side of the machine, so constructed that they may be set down over the rods which carry the usual denominational selectors. The brackets may be held in this position by means of angular members detachably secured thereto and extended under the usual brackets by which said rods are supported. The brackets for supporting the front end of the carboncarrler track are arched sufficiently to permit them to pass over the housing for the 95 denominational jacks, and they are connected at their rear ends by a cross-bar extending above the rear portion of the housing a-ndthe upper end of the casing for the usualthrust rods.

Provision may be made of brackets projecting forwardly from said cross-bar and having pivoted thereon the front cross-rod of the carbon-carrier track. Provision may also be made of forwardly-extending arms pivoted coaxially with the front cross-rod of the carbon-carrier track and connected at their forward ends by a rod or guide, which, when in its normal position, lies immediately above the rear edge of the usual rear no aper-table, the ends of said arms then restmg on the rear paper-table. This rod serves as a guide over which the usual webs pass to the platen. The webs, 1n passing from the carbon-carrier track to the rod at the forward ends of said arms, must be maintained at a suflicient height to pass over the raised front end of the housing of the denominational jacks, and for this purpose, provision may be made of a bar 1 connecting the two arms and lying immediately above the uppermost portion or peak of the housing. When a denominational selector is to be placed on the carriage or removed therefrom, the frame comprising the two arms and the connecting rod and bar must be swung upwardly and rearwardly. It will be seen that. according to the present invention, the fan-fold mechanism at the rear of the usual bookkeeping machine may be applied thereto without any change in the bookkeeping machine.

Other features and advantages will here inafter appear.

In a bookkeeping machine of the Underwood-Hanson type, a typewriter 11 having a frame 12 rests on the casing 13 of a computer 14, which is controlled by the numeral keys of the typewriter, and the computer casing 13 rests on a stand 14 comprising a top 15 and supporting-posts or legs 16, of which the two legs on each side are connected by members 16.

The typewriter 11 comprises-a platen 17, mounted on a platen-axle 18, rotatably supported in a traveling carriage 19,'which is the notches of the notched rod 30.

supported at its rear on a rail 20 fixed on the typewriter-frame 12. Associated with the platen is a rear paper-table 21 over which work-sheets or webs are directed to the bottom of the platen. When used'as a part of the bookkeping machine, provision is-made of bracke s 22 attached to the, rear of the typewriter-frame 12 at each side thereof and carrying at their upper ends-a bar 23 on which may be supported one or more sets of denominational jacks (not shown) and a housing 24 for each set of such denominational jacks. Said housing 24 is highest at its forward end and slopes downwardly toward the rear. At the rear of the housing 24, a casing 25 for the usual thrust rods (not shown) eX- tends downwardly to the rear of the computer casing 13 and is attached thereto.

For use in a bookkeeping machine, the carriage is provided at its rear with brackets 26 extending rearwardly and outwardly and having upwardlyextending ends 27 in which are mounted a rod 28 along which a denominational selector 29 may be moved and a notched rod 30 having its notches at letter-spacedistances, the denominational selector 29 being held in adjusted position by engagement of a tooth 31 thereon in one of When the carriage is traveling through a computing zone. a tappet (not shown) carried by the denominational selector 29 engages successively the forward ends of the denominationaljacks (not shown) pivotally mounted in housing 24, and selects the denomination in which digits are to be indexed. The computing mechanism and the denomination-selecting mechanism forming part thereof may be in general similar to that dis closed in the patent to Richard M. Becker, No. 1,296,354, granted March 4, 1919.

Inasmuch as the present invention contemplates the use in a bookkeeping machine of the features of a continuous-billing or fan-fold machine, the axle 18 of the platen 17 is journaled in ends 32 of a platen-displacing frame 33, said ends 32 being pivoted on a shaft 34 at the front of and above the normal position of the platen-axle 18. The platen-axle is provided at each of its ends with a gear 35, which meshes with a broad pinion, 36 fixed on the shaft 34, and the broad pinion 36 alsomeshes with a gear 37 similar to gear 35 and fixed on the inner end of a stub-shaft 38 journaled in the adjacent end of the carriage 19. The platen may be rotatedby means of either of the fingerwheels 39 or by the usual line-spacing mechanism. When the webs, indicated in general by 40, are to be straightened under the platen to permit the withdrawal of the interloaved carbons in the usual manner the platen is swung upwardly above the shaft 34 to the position shown in Figure 7, the webs 40 then being drawn forward and 130 raeaaoe gaged by means of the usual ga e 41 adjustable on the gage-bar 42 mounte on a front collatinw table 43 which forms part of the platen-displacing frame.

In order to displace the platen 17 upwardly to a suflicient extent to straighten thereunder the Webs 40 used with the fanfold mechanism, the broad pinions 36, WhlCll may be described as oversized, are very much larger than in the usual fan-fold machine, thus permitting the shaft 34 to be positioned at a greater distance than usual from the platen-axle 18, so that the platen may be displaced upwardly to the desired extent. Such increased displacement of the platen is rendered necessa by the position of the housing 24 above W ich the webs 40 must pass.

At the rear of the machine, provision may be made of a carbon-carrier 44 mount ed for forward and rearward movement on a track or frame 45 comprising a front member 46, a rear member 47 and a plurality of connecting members 48, two of said members 48 having on the upper sides thereof rails 49, with each one of which cooperate grooved rolls 50, as shown in Figures 5 and 6. The rolls 50 are rotatably mounted in the ends of members 50* secured to the lower face of and at opposite sides of a base-plate 51 of the carbon-carrier, and the movement of the carbon-carrier 44 along the rails 49 is resisted to a certain extent by spring brakes 52 bearing on the lower faces of the rails 49. The carbon-carrier may be moved to the rear by means of a handle 49 of the usual form.

To support the carbon-carrier track 45 at its forward end, provision is made of brackets 53 which may be readily attached to and removed from the rods 28 and 30, each bracket being cut away to form a slot 54 to receive the rod 28 and also cut away to form a shoulder 55 to rest on the top of the rod 30. It is a desideratum to provide means for attaching the brackets 53 to the typewriter carriage without changing the usual construction of the carriage and Without making any openings therein to receive screws or other attaching devices. To this end, the brackets 53 are held in position on the rods 28 and 30 by means of angle-plates or clamps 56 placed on the outside of the upwardly-turned ends 27 of the brackets 26 and having their lower ends fitting under the laterally extending portions of the brackets 26, each of the plates 56 bridging over the upright end 27 of the corresponding bracket 26 and being connected to the latter by suitable fastening means, such as bolts 58.

The brackets 53 are arched so as to pass over the housing 24 during the lateral movements of the carriage and terminate at points slightly above the level of the rear end of the housing 24. The rear ends of the brackets 53 are connected by a cross-bar 59 which extends over the rear end of the housing 24 and furnishes a support for the ten ward end of the carbon-carrier track 45, the front member 46 of the latter, being pivotally mounted on brackets 60 secured to the bar 59 and extending slightly to the front thereof.

As a result of mounting the front member 46 of the track 45 in the position described there is a considerable gap between front member 46 and the rear end of the paper-table 21, and it becomes necessary to provide means for guiding the Webs 40 above the raised front portion of the housing 24. For this purpose, provision is made of arms 61 pivoted on the brackets 60, so as to turn about the same axis as the front member 46, and normally extending forwardly with their down-turned forward ends resting on the rear paper-table 21. Supported at its ends on the arms 61 is a bar 62 which lies directly over the raised forward end of the housing 24, thus preventing any interference between the latter with the webs 40 when the carriage is moved laterally of the machine. Without this bar 62, the webs 40 would be liable to be caught on the sides of the housing 24 or on the usual screws 63 which project from the upper surface thereof. The arms 62 are connected at their forward ends by a rod 64 which. also serves as a guide for the webs from which they pass downwardly between the rear paper-table 21 and the platen 17. Side gages 65 may be mounted on the rod 64 and may be secured in adjusted position thereon by screws 66. The arms 61, the bar 62 and the rod 64 constitute a frame or intermediate web-guide which may be swung upwardly and rearwardly to permit adjustment of the denominational selector 29 along rods 28 and 30 when such adjustment is to be effected. It will be evident that, when the frame comprising the arms 61 is swung rearwardly, the curved upper edges will be brought into engagement with the upper face of the cross-bar 59, and that the frame may be left in this position until it is desired to restore it to its normal position.

At its rear end, the carbon-carrier track v may be provided with a guide-rod 67 on which are adjustably mounted two side gages 68, one of which is provided with'an overhanging portion 69 to prevent the webs 40 from being lifted above the side gages 68.

At its rear, the track 45 is supported by a rail 70 on which run rolls 71 rotatably mounted on arms 72 extending downwardly from the frame 45 and having their lower ends 74 extending beneath the rail 70 so as to maintain the rolls 71 in contactwith the rail 70. In said, prior application,

Serial No. 489,990, the rail corresponding to rail of the present machine was supported by a bracket or brackets attached to the typewriter frame at its rear, an arrangement which rendered difficult access to the rear of the typewriting machine. To overcome this disadvantage, the support for said rail 70 is mounted on the stand on which the computer casing 13 rests, thereby spacing the upper end of the support 75 sufficientlyto the rear to permit ready access to the back of the typewriter and the computer casing.

The support 75 comprises a bar 76 to be positioned on the top 15 of the--stand 14 and provided with openings 77 whrch may be brought into register with openings 78 and 79 in the top 15 and in motor-frame 80, so that the motor-frame 80 and the bar 76 may be held in position by screws 81 extending through said openings 77 and 78 and threaded into the motor-frame 80. In machines of this class, the motor-frames are usually attached to the stand by screws in the position shown, and, in order to secure the cross-bar 76 in the position described, it is necessary merely to use screws 81 of greater length than ordinary. The support 75 also comprises side members 82 provided at their lower ends with laterallyextending hooks 83 which maybe moved into posltion to embrace the ad acent legs 16 by movement inwardly from the sides, the side members 82 being held in final position on said legs 16 my means of setscrews 84 threaded in the sides of said hooks, so that they may be tightened against the legs 16 to clamp the'side members 82. in position. The side members 82 are also connected by means of screws 85 with brackets 86 extending rearwardly from the ends of the cross-bar 76.

To further strengthen the support 75, provision is made of a cross-bar 87 near the upper ends of the side members 82 and secured thereto by screws 88. The rail 70 is provided with plates 89 extending therefrom and so spaced as to correspond with the spacing of the upper ends of the side members 82, so that the plates 89 may be placed on'the upper ends of the side members 82 and secured thereto by suitable fastening devices 90. As herein disclosed, the plates 89 are provided with ribs 91 to enter grooves 92 in the upper ends of the side members 82. It should be noted that the structure of the support 75 is such that it may be attached to the stand 14, without changing the structure of the latter in any respect, the lower ends of the side members 82 being clamped on the legs 16 and the bar 76 being secured to the top of the table by screws 81 passing thr zough the same openings as the usual screws for supporting the motor-frame 80.

Althou h the. weight to be supported by the rail 0 is comparatively small, it is necessary to make the support 75 of considerable strength so as to prevent bending or breakage of the same by accidental collision therewith, the support 75 extending in such a direction from the stand that it is likely to be struck accidentally especially when the track 45 is removed from the rail 70.

It should be understood that the engaging portions of the typewriter-frame 12, the computer-casing 13 and the top 15 of the stand 14* are so constructed that, when assembled as shown in Figure 7, the movement of the carriage 'will be parallel to the rail 70.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
